Significant resistance has been seen with pyrethroids in the Red River Valley. BASF is introducing a new insecticide to combat that resistance called Sefina. Technical Product Manager Christa Ellers-Kirk says Sefina has a very unique mode of action. It causes the soybean aphid to become uncoordinated and stop feeding. “It starts to stimulate them so the insect feels like someone is poking it or bothering it so it is agitated and starts moving around. You may see the bug boogie on the leaf, but they’re not feeding and are starving to death.” Sefina is not a restricted-use product and has a wide window for application. This insecticide is also compatible with pollinators and other beneficials.
